Answer:

3

Step-by-step explanation:

Solve for x:

-6 + x = -3

Add 6 to both sides of the equal sign so -6 cancels out on the left side

+6 - 6 + x = -3 + 6

x = - 3 + 6

x = 3


I hope this helps! Good luck with your schoolwork :)

Show that the line with equation 4y+3x=44 is a tangent to the circle with centre (5,1) and radius 5.
viktelen [127]

When a line is a tangent to a circle then the point of a tangent on a circle is perpendicular and also equal to the radius

So for perpendicular.

                                            P = \frac{ax+by+c}{\sqrt{a^2 + b^2} }

4y + 3x - 44 = 0

So, a = 4

      b = 3

      c = -44

      x = 5

      y = 1

Putting the values in the formula, we get

P = -4.2

Since the radius of the circle 5 is not equal  to P, The line is not a tangent to the circle.
